But our ears are very sensible to some things, and ears are more sensitive at 100Hz than 50Hz, so if you cut too low, or if you boost low frequencies (at the expense of upper bass), your ear can identify that as a short throw, but it isn't, as proved by the void paper. There's the reason why band pass enclosure are generaly qualified to short throw: first reason, they have limited frequency response, and lower max level, this why ears identify it as short throw

Another point: For max SPL, impact, and "throw" feeling, you must have your tops and bass cabinet in perfect phase (delay). You must make measurements with software like Smaart. The difference between a bad and good setting can be night and day.

Hey Dj Maestro,

In my experience if you want long throw for outdoor use you cant beat a nice line of folded horns, at least 4 i would say.

I currently have only 2 MTH4654 so cant say how they work in a line. But the two i have sound very very full and will cover a couple of hundred people outdoor. They sound great indoor as well, they seem to just fill the room up with bass with ease. Folded horns and front loaded boxes seem to sound consticed and hollow next to them. They also get below 40hz with 1 box.

With other words if i want 'throw and feel the bass" i must look a bassenclosure that hits hard in the 100hz area.What are the freq range, we human can feel and heared like far throw?

Will something like the mhb- 46 then do a better job..something that can deliver sub bass and kick?or a folded horn..

All scoops have a dip in frequency response near the kick frequency range. So they can make bass, but for kick, you need to add a "Kick Bin". Without Kick bin, you can have this sensation of "bad throw" because the dip in frequency response of the kick. Most scoop must be cut between 70/90Hz, then the kick bin takes over.

If you want a all in one cabinet, bass + kick, the hybrid like MHB-46 and MHB-4818 are. They are very physical, "in your chest" and have the "long throw feeling". MHB-4818 has been measured at 106.8dB at 1w/1m in the 50/120Hz range (110dB 1w/1m at 200Hz!)

All others cabinets with long horn (2 meters and more) need a kick bin. MTH-4654 needs a kick bin.

In my experience if you want long throw for outdoor use you cant beat a nice line of folded horns, at least 4 i would say.

Throw is more related to psycho-acoustics than a real level difference between designs (as shown in the Void paper). All cabinets in a PA system must be considered as a single entity: if one cabinet is not in perfect phase with others cabinets, if the frequency response has dips, it can radically change sound perception.

many thanx marc and massive for your advise...In my country most dj's use scoops, but mostly with not the recommended drivers, they just buy drivers(mostly china made drivers) and put them in scoops, they dont know better...I always have use reflex bins (g sub with p audio drivers 600w)but now i own 4 18LW2400.. I just wanna the best output from those speakers...I am looking the mhb 46 for a while but im not sure if i can go with it..I have already 4 ms46 indoor they hits hard, but outdoor i can not feel the bass after 3-5m.

Allright, will folded horn give me also bass and kick or only bass for outdoor use

look forward to hearing how your first box sounds. I have only mth no mhb but they do look very good on paper.

I have never heard invaders but they also look very good. I would like to hear some. DIY soundsystems are not very popular in Sydney. As far as I know i am the only person in Sydney with DIY bass horns. I would love to stand corrected on this. Anyone?
